Appli i n filed March 26.1906. Serial No. 308.069.

To all whom it may concern:

Beit known that LULYssEs S. JAMES, a citizen of the United States, residing at Newark, in the county of Essex and State of New eral type as that disclosedin my pendingapplication, Serial Number 263,064, filed .May31,1905. Thepresehtconcentratorpossesses all the advantages possessedby that covered in said application.

An oreconcentrator made in accordance with my invention involves a longitudinally or endwise reciprocatory table. is made up of 'two sections, one of which is the concentrating portion proper, while the other of which constitutes a slime pan.

' the slime portion or pan, but the major part .of the concentration is performed upon said concentrating portion, for which reason such designation has been adopted. By virtue of eral values in the slime delivered into or onto said slime portion, a proceeding which has heretofore, so far as I am aware'not been possible.

this specification, T show one simple adaptation of said table, which to enable those skilled in the art to practice said invention, I WIll SGt forth in detail in the following-description, whilethe-novelty of said invention :w1ll be included in the claims succeeding said description' The table is of such characterthat it is not subject to vertical'vibration; it and the parts upon which the table is mounted are/strongly braced.

The invention has other objects and advantages which with the foregoing will be hereinafter treated at length.

being on the I 'Similar -numerals refer to like parts present case the table consists of two sections as 3 and 4. As the greater part of the concentration of the ore is performed upon the portion-3 of the table, I will designate the same as a concentrating ortion, although from what has been hereinbefore stated it will be understood that the slimes are profit ably worked over or concentrated upon the slime ortion 4. The two sections are 'connecterf in a flexible manner, the hinge lying between the two being denoted in a general way by 5 and as represented best in Fig. 1, saidhinge or dividing line is oblique to the line of motion of the table, such lineof motion being longitudinal. I have not shown any means for longitudinally reciprocating --the table 2 for the same constitutes no part This particular of the present invention.

' mechanlsm may be of any desirable kind and may be of substantially the same type as that now generally in use which is adapted to give to the table initially on its forward stroke a slow movement, and finally,'or on the completion of such stroke, an accelerated motion to drive the mass on the table forward. On the return stroke of the table suchmechanism will cause first a ra id and in its make-up aseries of longitudinally extending slats as 6 covered with some suitable material as 7 upon which the concentrating is done. The material 7 may be, for example, linoleum. The longitudinally extending :slats 6 larea'crossed on their under sides by cross bars as 8, the slats and cross bars, being usually made of wood, whereby the table can be made inexpensively while it is sufficiently strong and stable to withstandthe hard usage to which a table is put. Some of the cross bars 8, as clearly shown in Fig. l, are intersected by the hinge or dividing line 5. Those cross bars 8 which are located directly under or form part of the concentrating portion 3 of the table are subjected to unusual stress which tends to distort or break the same. To prevent distortion of these particular cross bars, I provide stiffening or reinforcing members in connection therewith, and these stiffening or reinforcing members may be of any desirable character, although they are shown as being of channel form as indicated in Fig. 7. The reinforcing members 9 n ay consist of sheet metal properly shaped, or they may be in the form of castings to closely it the cooperat ing cross bars and to be united thereto in any desirable manner. They may be held in place by a driving lit or by friction or posi tive means may be provided for holding them in assembled rehntionv That part of the concentrating portion-3 of the table to the right of the hinge line 5' in Fig. l is upwardly inclined fromsaid hinge line and'the latter constitutes the base for said upwardly inclined or concentrating portion. In addition to this upward inclination of the concentrating portion, the latter is also oblique to the line of motion of the table. The angularity'of such concentrating portion may be varied to adapt the table to the particular character of ore beingworked and I will hereinafter describe a simple means for securing this adjustment.

The feed box for supplying pulp onto the table may be of any desirable character and may be mounted in any suitable way. For this purpose, I have shown a feed box 10 as fastened in some convenient way to the slime portion or pan of the table, and as crossiig the hinge line between said slime portion and the concentrating portion of the table, whereby the pulp is delivered directly' onto the head end of the table so that when it strikes the table it can be advanced therealong and can be also stratified, the mineral values in the mass which are the heavier 1" 1 x n 1 i +1 1 a set .ing 10 the bottom or the mass 01 ircc v 5 onto the top 7 of the tanle. The shines are i into the shine n n. lby reason oi.

' iiuid conch/Jen assisted by the r 7 j '5 I lne pulp is introduce of tne table er substa" junctien between the hinge line 5. the table are parallel rifiles as 12 which cross .table, the pulp is advancedtoward the tail thereof an the several constituents in which the pulp has been separated are moved cross- 7 5 wise of the table or toward the front thereof; the gangue moving more rapidly than the other materials. The gangue is, therefore, carried toward the front edge of the table and is discharged thereover between the dividing or hinge line 5 andthe tail of the table. The mineral values are'carried to ward the tail of the table with less lateral movement than the gangue, owing to their greater density and are discharged over the front of the table and over the tail end thereof.

. The Wash water is supplied to the table along a line oblique to the line ofmotion Y thereof and any suitable means may be provided for this purpose. For furnishing the wash water I represent a pipe 11 extending along the angular portion of the upper or rear edge of the table whichangular. edge as shown in Fig. 1 is at an acute angle to the Extending longitudinally of Isa the hinge line 5. These rirlles extend in the direction of line of motion of the table and are comparatively shallow so as not to re- 1,00 tard the lateral motion of the gangue after the same has been separated from the mineral values.

Along the rear of the table is extended a ledge as 13 which connects with the ledge or flange Mextending across the head end of the table, the flange 14 having its front end deflected upon a forward angle and extending into the ledge or flange 15 running along the slime portion of the table. The free end of this ledge or flange 15 extends short of the slime portion so as toprovide an outlet as 16 for the mineral values concentrated from the slimes which particular mineral values are I dischargedover the front of the table imme- 1'15 diately behind .the gangue, the gangue being delivered over the front of the table at a table tc'the front edge thereof substantially centrahy of the length of said front edge and near the hinge line 5. The ridge 17 with the flanges 1a and 15 present the marginal portion of the slime pan which has the outlet 16.

The ridge 1? oppositely inclined-faces as 18 and 19 both diagonal to the line of motion I The face 18 constitutes really 1', while the face 19 extends downward from said ridge. This ridge 17 prevents the coarse material from entering the slime pan although it does not prevent the slimes'from' entering said an owing to their character; The uppers ace of the, ridge or flange T which in the present case .is horizontally disposed,- merges into the inclined face 1,8- as clearly indicated in Figs. 1 and ,2. 1 The wash water and the water in the slimes contained within the slime pan 4 is in a quiet .or

' still condition so as notto: ofie'r any resistance to the fiow of the slimes into said slime P When the slimes enter the slime pan the mineral values therein gravitate toward the bottom of the liquidand on the forward motion of the table are projected ontothe inclined surface 18. The ridge 17, however, of which said inclined surface forms apart, prevents the mineral values which have de scended in the slimes from being washed over the top of the ridge and this result is aided by the wash water flowing over the top of the ridge. The mineral values in the slimes are after precipitation projected on the forward motion of the table onto the inclined surface and arenot carried thereover as previously set forth, .butthey are moved along said inclined surface and are directed through the outlet 16. The wash water free or mineral values and mixed with tailings or refuse from the slime pan passes over the front ledge 15. By the provision of the slime pan I -am enabled to save mineral values in slimes which have not heretofore been saved with concentrating tables as ordinarily constructed.

The framing for supporting the table 2 may be of any desirable character, although in Figs. 4- and5 I have represented an ad ,vantageous form of framing and the same involves in its make up a stationary member denoted in a general .way by .20 and a swinging-member as 21, the swinging member being hingedly mounted and being directly associated with the concentrating portion 3 of the table by virtue of which the angular" adjustment of said concentrating por ion] may be readily obtained. The portion 20, asbest shown in Fig. 5, comprises two stringers, each denoted by 23, which converge toward the tail of the table. These stringers are prevented from inward motion bythe cross beams 24 fitted between and I suitably secured to the same, while outward motion of the two stringers is prevented by the tie rods or bolts 25 of any desirable number. The-two stringers 23 are cut away between their ends. as shown for example in .the deeper parts of the two stringers.

Fig. Land the diagonally disposed strut or brace 26 rests on the top of the cut away portions and bears near its opposite 'ends near the forward ends of shoulders produced by said cut away portions. The upper face of the brace or strut 26 is flush with orin' the same horizontal plane as the upper surfaczeof ee Fig. 4). This brace extends in the direction of the hinge line 5 and is located immediately under said line so as to prevent the table tipping in the direction of the said line. In addition to this the brace also strengthens the bed or foundation frame and provides a means" for 11 holding certain links. The hinges, each .esignated by 27, are also sus the two sections of the frame or bed of'the table. The axes of the several hinges 27 are alined and are in a vertical plane intersecting the hinge line 5. the bed or foundationframe, is shown as composed of two steel orother metallic bars, each designated by 28 and which extend-in the samegeneral direction as the stringers tained by this brace 26, the hinges uniting The hinge member 21 of 23, as illustrated in Fig. 5. Between the 'two bars or channel irons 28 the cross braces 29 extend, said cross braces having heads at their opposite ends fitted within the channels of said bars 28 and boltedor otherwise suitably fastened to the webs thereof. These cross braces or bars 29 prevent lateral vmotion both inwardly and outwardly of the two bars or channel irons 28. 'On the upper side .of the two cross pieces 24 at the left'in Fig.5

rests and is suitably fastened a b'eamBO, the upper face of which is in the same horizontal P ane as the upper face of the obliquely .dis-

posed brace or strut 26, the two parts last" mentioned abutting against each other'in or der to further strengthen the structure.

I flexibly support the table 2 in an advant'ageous manner so that it will not be susceptible to shocks or jars, but on the contrary will run smoothly and noiselessly. This resuit I accomplish by links of a novel character extending between the table and the bed or foundation piece for the table'which, as

will be understood, comprises stationary and hinged sections as '20 and 21,.respectively.

There are two series of these links, one series extending between the stationary member 20 and the table, and 'I will designate each in a general way by 31, while theother series, each of which I will'designate in a general way by 32,- extends between tha'swinging member 21 and'said table. Alljof elinks are of thes'aine general character so :that a detailed description of one will suffice for the remainder, and-in this connection particular reference may be had to Figs. 8 and 9, -where" in one of the links which extends between the member 20 and the table is shown in detail,- these two figures, I have shown a way of connecting the links with the respecj set into notches or slots in the opposite ends of the woodenbody and are fastened to the latter in some suitable way as by rivets. The upper flexible strips 34 are fitted flatwise against one of the side faces of the respective cross bars 8 and laid againstthe flexible strips are facing pieces as 35 of wood for example, bolts 36 serving as a suitable means connecting the facing members 35,-

upper flexible strips 34, and cross bars 8.

The lower strips 34 are fitted between the sections of clamps as 37, the sections of which are held together by bolts or any other suitable manner, and one section of each of which clamps is fastened to the sections of the stationary bed or foundation member 20..

With respect to the series of links 32 they are connected at their upper ends with the angularly adjustable or concentrating portion of the table 2 exactly as are ,the upperends of the links 31 connected with the slime The links 32, however,

portion of the table. are connected at their'lower ends adjustably with the swinging section 21 so that should there be any imperfection in the irons 28, such 35 imperfections will not prevent the concentrating portion of the table from being brought to an absolutely horizontal position when the'table as a whole is set up. The lower flexible strips 34 of the links 32 are held in placeby clamps as 38 forming parts of brackets as 39 supported for vertical adjustment by the sides of the swinging member 21. In the bodies of the several brackets 39 are formed vertically disposed longitudinal slots through which screws as 40 are passed (seeFigs. 10 and 11.) by which vertical ad-- ,justment of the several brackets can be obtained, this being accomplished by loosening up the screws. After the adjustment is secured it can be maintained by tightening up the screws. To facilitate the elevation\of the respective brackets they may be provided, as shown in Fig. 11, with heads as 41 which overhang the upper edges of the sides of said member 21, and through which are tapped adjusting screws as 42 to engage said sides. p I Any desirable means may be employed for elevating or lowering the swinging section 21 thereby to regulate the angular position of the concentrating'portion 3 through the intervention of the intermediate links 32 as 'will now appear.' Supported by a suitable bearings upon the stringers 23 near the tail end of the table is a shaft as 43 having at one end thereofa worm-gear as 44 meshing with a worm as 45 on the shaft 46, said shaft being provided with ahead as 47 at one end, as

43, through the intermediate worm gearing described, can be turned so as to carry cams as 48 and :49 against the outer. cross bar 29 to angularly adjust the concentrating portion 3 of the table.

vate the rear side of the table slightly more than the front side of the table .to preserve the obliquity to which I havehereinbefore referred. The shaft 46 is shown as surrounded by a spring 50 hearing at its ends against the head 47 and against the bearing The cam 48 has a greaterv throw than cam 49, as it is necessary to eleshown in Figs. '4 and 5. By turning the head '47, the shaft 46 and consequently the shaft 70. V

for said shaft, the spring serving to positively prevent backward motion of the two shafts, while the table is in action. Were notthe spring present the two shafts. would be turned backward while the table is in motion, and thereby affect the adjustment of the concentrating portion thereof.

The table involving my invention comprises really main and auxiliary concentrating portions. Practically the major part of the concentrating is done upon the mam portion. In other words, the .pulp or heavier material is worked over on this mainconcentrating portion, while the finer particles mak-- ing up the slimes are worked on the auxiliary portion. Both portions of the table, therefore, are simultaneous in action. The main or. concentrating portion 3 of the table has between the ridge 17 and the hinge line 5 a horizontal portion 3', as shown clearly 'in Fig. 1 on which the material when it is first delivered onto the table can freely spread out, this insuring the-clean separation ofthe gan ue from the mineral values.
